You wouldn't end up contracting with some weird local nerds for critical systems?

What local nerds? Usually you go to a so called "Systemhaus" for that. Like a contractor or I think you'd call it managed service provider. Some municipalities (or companies for that matter) get everything done by them, some have some admins but need some support in more complex matters. Completely professional and not some side gig, lol...

It doesn’t say that each of the services they are using is some local small ISP, the whole point is to show they are also using large US companies.

Also, it would probably be easier to get a real human on the phone or proper support from the local nerds compared to Google.

I’ll take rsync.net

over OneDrive,

all day long.

As one example.
